Well, actually I never won't pronounce myself as something like a guru or whatever. But today Karin from the product management team asked me to review the source code of an external developer. I was really amazed they came to me to do this. So the guy really did a good job I think, the only thing was that he did almost no javadoc inline documentation.
So, now he fixed this, so I'm pretty happy with this small tool for our platinum customers team, also if we'd have to fix bugs on our own.
